The countdown is on to Census night, which takes place on Sunday, April 3 this year.
Millions of people across Ireland are required to fill out the form, which is a count and account of everyone in the country on that night.
There are 11 household questions and 33 questions to be completed for up to six individual people who are present in the household on census night. Topics include age, marital status, gender, place of birth, occupation and housing characteristics.
